Star Wars: The Last Jedi is mired in secrecy. For some fans, that's just how they like it. Others though, they want to solve the mystery, and propose theories to explain every little detail about the movie. One particular theory gained a lot of traction over the week, so much so that it prompted a response from the Jedi Master himself, Mark Hamill.

The theory says that it's Luke, and not Supreme Leader Snoke, who is the true big bad of the whole trilogy. Or that, at least Luke is a villain in addition to Snoke. A lot of the theory owes itself to Luke's general demeanor, his line about "it's time for the Jedi to end," and the fact that his face is looming in the background of the film's posters. In response to this, Hamill tweeted:

NEWS FLASH for all you "Villains Looming at the Back of Posters" theorists: Luke was ALWAYS the villain! (from a certain point of view) 😲 pic.twitter.com/4FzxDbFd4VOctober 17, 2017

Hamill is known for playing with his fans. He's said he thinks of Daisy Ridley as a daughter (a joke on the mystery over who Rey's parents are) and has called actor John Boyega his son (same joke, same mystery of unknown parents). So I don't think he's being serious here. It's just fun to see the star troll us a little.

Disney itself seems to be having fun playing with fans about the theory as well - this month the company unveiled a cinema display with one side seeming to represent the Light Side of the Force, the other representing the Dark Side. Luke, as it turns out, shows up on both sides.
